NASA mission finds widespread evidence of young lunar volcanism

Posted October 13, 2014 by

NASA/GSFC/Arizona State University image NASA’s Lunar Reconnaissance Orbiter has provided researchers strong evidence the moon’s volcanic activity slowed gradually instead of stopping abruptly a billion years ago. Scores of distinctive rock deposits observed by LRO are estimated to be less than 100 million years old. This time period corresponds to Earth’s Cretaceous period, the heyday…
